The Critical Care Resuscitation Unit – the CCRU- is a novel resuscitation unit for critically ill non-trauma adult patients who are transferred from outside hospitals for specialty care at the University of Maryland Medical Center (UMMC).  The CCRU, located on the 6th floor of the new trauma tower in the R Adams Cowley Shock Trauma Center, is staffed 24/7 with attending critical care experts and experienced critical care staff.  The CCRU is based on the highly-effective Shock Trauma Resuscitation Unit model, and is designed and developed for collaboration with referring facilities and pre-hospital transport providers as well as for immediate resuscitation of time sensitive emergencies.  

The CCRU is developed to ensure patients at referring facilities with time-sensitive critical illness who require transfer for specialized care can get to UMMC as fast as possible and once at UMMC, quickly receive time-sensitive therapeutic interventions.   On arrival, the CCRU is capable of aggressive resuscitation, rapid initiation of invasive hemodynamic monitoring and complex supportive therapies (continuous renal replacement therapy, intra-aortic balloon counterpulsation devices, extracorporeal membrane oxygenation cannulation and management, continuous electroencephalographic monitoring, and resuscitative endovascular occlusion of the aorta).  When relevant, the CCRU’s processes effect immediate transfer to operative theaters.

The CCRU attendings together with UMMC sub-specialists provide consultation to referring physicians through Maryland Express Care (MEC) and recommendations for patient management are provided even before the patient is transferred from the sending facility.  In addition, the CCRU works very closely with MEC and provides direct medical consultation to the transport teams en route to the CCRU.  Based on the data provided by referring clinicians and the transport teams, the CCRU readies the patient room with appropriate equipment and therapeutics prior to arrival of patients, and subspecialist attending consultants wait in the ready.  After initial resuscitation and possible operative management, patients will be transferred to the appropriate sub-specialty UMMC ICU for ongoing care and to allow the CCRU to be ready for another patient.

The CCRU accepts adult patients with a wide range of non-trauma life threatening conditions, including and not limited to:

  • Cardiac Surgery and Cardiology
    • Cardiogenic shock 
    • Severe ongoing cardiac ischemia 
    • Severe valvular dysfunction requiring surgical consideration
    • Acute ascending aortic emergencies
    •  Massive pulmonary embolism
  • Acute and Emergency Surgery
    • Severe mesenteric ischemia
    • Severe acute pancreatitis
    • Perioperative hemodynamic instability
  • Vascular
    • Aortic emergencies
    • Acute vascular insufficiency 
    • Other aneurysm and pseudoaneurysmal hemorrhage
  • Soft Tissue Infections
    • Necrotizing Fasciitis requiring surgical intervention
  • Liver Failure
    • Fulminant hepatic failure
    • Acute decompensation of chronic liver failure requiring intervention (e.g. TIPS) and/or transplant evaluation
